blue ox sway pro question

Right now with my Blue Ox sway pro, the bar chains attach on the 8th link as measured from the bar end. The rear wheel well of my truck squats 1 and 5/8 inch and the front wheel well rises 3/8 inch as compared to no trailer attached. Shouldn't I be getting zero rise on the front? How many chain links can I tighten the bars and still be safe? Is there a minimum number of links that should be maintained between the bar and where the chain hooks to? Also, can the receiver shank be safely rotated 180 degrees and the hitch head remounted to get more height on the hitch ball? Thanks.
  • Here is the direct quote from the Installation guide, I tow in the 8th or 9th link from the top opposite the U bolt

    " Insert the 9th chain link from the top
    (opposite the u-bolt) into the slot of the latch. Using the wrench, rotate the latch
    counterclockwise until the lock pin engages in the lock pin hole.
    Note: Adjustments to the number of links used may be necessary due to certain
    driving conditions and/or changes to the trailer after initial setup. Advancement to the 10th or 11th link from the top is recommended to compensate for these changes."
  • What is your tongue weight and what bars are you using? As others stated, Blue Ox says start on the ninth and go up one more if needed.
  • I have used both the 8th and 9th link but prefer the 9th link. We traveled to the coast and back over the weekend S East into the wind going and N West with a tail wind going home, tt was straight and true both directions (two lane roads) Last month we used I35/I37 to Corpus and had no sway or pushing issues from large trucks. The Blue Ox was a major improvement over the Eaz Lift we had been using the past several years.
  • Having no experience with a Blue Ox Sway Pro, I can't answer your question. However I am seriously considering one.

    A question for: are your bars sized right for the trailer tongue weight? From what I have read, too light of bars will not give you the lift you want to transfer enough weight to the front of your tow vehicle.
  • It's not necessary to get full front axle weight restoration on all vehicles.

    But, in the OPs case it sounds like trying 1 or two links righter might be a good idea. Another recommendation from Blue Ox is to have ~2" of bar deflection. I tried 1.5" at first and felt some porpoising, so I took up another link which put it at 2.5" and now it rides level over even the worse road heaves (my mountain drive has a couple slow active land slides the highway goes though. I've caught air a couple times because it changed so much in the course of a week).

    As said above, the instructions say start at the 9th link from the loose end. There should be 16 links all together so you'd would start at the 7th link from the U bolt. You can flip the shank. If you can't get enough height out of the standard shank then let Blue Ox know and they'll swap it out for you. The ball should be between equal to 1 inch higher than the height of the leveled coupler.

    As to how many links you can safely use, I asked Blue Ox this question. According to Blue Ox you can use as many links as you needed to level the truck. There's no minimum amount of links that need to be maintained below the latches. They've had people report to them that they've used every link available. Using more links should not hurt the bars.
  • Per Sway Pro instructions, ninth chain link from the end opposite the u-bolt should be inserted into the slot of the latch. You may have to use the tenth or eleventh link from the top depending on conditions. The shank can be inverted (long end up/down)to raise or lower the front of the trailer. Check the sticky in the towing section for a discussion on whether the vehicle should be level or how much rise you should get on the front.


    Good luck, and enjoy your hitch.
